The invention relates to a strain-sensitive resistor, comprising a resistance layer arranged on a support element and an electromechanical transducer produced with this resistor. An increase in the electrical measured signal picked off across the resistor is achieved in a simple way by the support element () having a recess () on its surface () which, when the support element () is subjected to mechanical stress in at least one area of the surface () of the support element () in which the resistance layer () is positioned, produces a ratio between the two main strain directions (L, T) of the resistance layer () which differs in magnitude.

Method of producing a strain-sensitive resistor arrangement

A method of producing a strain sensitive resistor includes matching an area of a film insulating layer to a shape of a recess in a surface of a support element. The film insulating area is applied to the support element so that the area of the film matching the shape of the recess is congruent with the shape of the recess. A resistive layer comprising strain-sensitive resistors is applied to the film insulating layer and the film insulating layer and the resistive layer are applied to heat treatment.
